Need opinion on fender P

A guy in my town is selling this Fender Precision. The serial number at the headstock refers to 1977.
He says the everything is origin.
I tryed it. It plays great, the action is low, although the sound is a little j-bass like (a little softer that I would expect for a p-bass).
Anyway, here are the pictures I take, so please tell me your opinions. Is it a '77? Everything origin etc.
Thanks!

From what I see, it looks like it could be the read thing. It's really hard to tell without seeing more 'interior' details though. If it is a 77, then it's in amazingly good shape...look how clean and shiny those tuning heads are... I played a 77 Fender about an hour ago, and it didn't look near as nice.

how much is he asking for it?
an original Fender Precision Bass 1977-1979, Blond is valued at
-prices are listed, low to high, excellent condition.
$1,100 to $1,600 (usd). if he's asking more than $500, tell him you need to see under the neck joint, to confirm it's authenticity. if its under $500, buy it. very nice looking bass.

No Serial on the heel plate is problematic as a 70's should absolutely have a serial number. Remove the neck and look at the neck below the truss rod, there should be a date stamped there.

Nope. There's not supposed to be a serial on the plate. It's on the headstock, as are all Fenders from 76 on. I bought a Precision new in 76, so I know. I think it's legit myself. natural was a very popular color in that era.
